Abstract
Here, we present the first reported case that used sacral neuromodulation as a treatment option for bladder neck obstruction in a 48-year-old man who presented with a long-standing history of lower urinary tract symptoms such as storage and voiding symptoms unresponsive to conservative and medical treatments, including chemodenervation. The patient was diagnosed with primary bladder neck obstruction (PBNO) using a urodynamic study, voiding cystourethrography, and cystoscopy. Sacral neuromodulation was used because the patient refused bladder neck incision because of the risk of retrograde ejaculation. The patient reported significant improvement in symptoms with no obstructive pattern on follow-up uroflowmetry after six months. The use of alpha-blockers, bladder neck incision, and Botox injection into the bladder neck to treat PBNO has been reported. The successful use of sacral neuromodulation to treat PBNO has not been reported before.
